Abstract
The utility model discloses a high-carbon steel atomizing and air-cooling device which solves the problem of poor effect of cooling a high-carbon steel wire after spinning and coiling in a rolling track. The technical scheme is as follows: the high-carbon steel atomizing and air-cooling device comprises a blower fan positioned below the rolling track, and an atomizing nozzle is arranged in the position of the air door of the blower fan through a support. The high-carbon steel atomizing and air-cooling device has simple structure and particularly has good cooling effect on the high-carbon steel wire spun on the Stelmor cooling line with strict cooling requirement. The temperature of the spray-cooled wire is 10 degrees to 50 degrees lower than the non-spray-cooled wire, and the speed of cooling prior to the corresponding phase transformation is increased by 13 to 20 percent.
Description
Technical field
The utility model relates to a kind of air cooling equipment of steel industry, a kind of specifically high-carbon steel atomizing air cooling equipment.
Background technology
Controlling cold is the variety steel production of the important step of wire rod rolling, especially high added value.Cold water-cooled and the air-cooled dual mode of being divided into of wire rod control haply, wherein water-cooled is mainly carried out before weaving silk, and air-cooled be that finish on the stelmor roller-way back of weaving silk.Wire product is weaved silk and is transported with setting speed on the stelmor roller-way after the lopping, the roller-way below is provided with one or more groups big air quantity blower fan simultaneously, require to formulate different roller table speeds according to different cooling control technologies, rotation speed of fan and throttle opening, in the hope of obtaining desirable metallographic structure, good intensity and plasticity guarantee the serviceability of product in follow-up deep processing.
And in the middle of the carbon steel wire rod with high actual production, tend to find that the cooling blower ability can not satisfy the requirement of product to cooling velocity.High-carbon steel especially hypereutectoid steel (phosphorus content is more than 0.77%) needs cooling fast, and the sorbite rate in the raising metallographic structure will avoid occurring in the metallographic structure network cementite and martensite to guarantee the extension property of material simultaneously to guarantee the intensity of product.The control of network cementite is difficulty the most wherein, and the most direct way is exactly the cooling velocity of accelerating before the phase transformation, allows metal phase change finish fast, and the compression cementite is separated out and connected space into the net.And strengthen fan delivery and improve the circle spacing is the measure of generally adopting at present, but the raising of fan delivery and roller table speed all has certain limit, reaches maximum quantity of wind still may not necessarily satisfy production requirement, especially hypereutectoid steel to phase transformation before cooling rate require higher.Improving the blower fan cooling capacity is the key that solves cooling control technology.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of good cooling results to be provided, the high-carbon steel atomizing air cooling equipment at the quick cooling of back stelmor roller-way high-carbon steel of weaving silk simple in structure, that improvement cost is low.
Technical scheme comprises the blower fan that is positioned at the roller-way below, and the air door place of described blower fan is provided with atomizer by support.
Described atomizer by the inner sleeve that is provided with air inlet, be provided with the outer tube of water filling port and the mouth core that is communicated with inside and outside sleeve pipe constitutes.
By the atomizer that is provided with at the air door of fan place, the wind that the atomization gas that is sprayed by nozzle is come out by blower fan brings in the roller-way and directly contacts with wire rod, utilizes the high heat capacity ratio of water to take away heat, realizes the quick cooling of carbon steel wire rod with high.
Described nozzle air inlet feeds compressed air, and water filling port feeds cooling water, and compressed air and cooling water form the atomization gas ejection after the mouth core mixes, and droplet is small and light, can be evacuated in the roller-way by blower fan.
Blower fan under the described roller-way can be provided with at least one group as required, and described atomizer also can be as required be provided with at least one along the air door place of blower fan.
Beneficial effect:
1, simple in structure, only need existing blower fan is just simply transformed and can be moved, it is low to transform this one-tenth;
2, for the carbon steel wire rod with high good cooling results after weaving silk on the demanding stelmo line of cooling, the wire temperature that cools off by aerosol hangs down 10～50 ℃ than the wire temperature that non-aerosol cools off especially, and cooling velocity increases 13%-20% before the respective phase change.
3, the metal lographic examination of wire rod is shown the obvious minimizing of separating out of harmful tissue such as network cementite, the tissue and the performance of wire rod are more even, and fluctuation reduces, and the mechanical property fluctuation reduces, and the carbon steel wire rod with high cold-forming property of production is good.
4, reduced environment temperature, improved operating environment.
Description of drawings
Fig. 1 is the utility model scheme of installation.
This structure of nozzle of Fig. 2 schematic diagram.
Wherein, 1-roller-way, 2-wire rod, 3-blower fan, 4-atomizer, 4.1-water filling port, 4.2-outer tube, 4.3-air inlet, 4.4-inner sleeve, 4.5-mouth core, 5-support, 6-water inlet pipe, 7-air inlet pipe, 8-air door.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
The wire rod 2 of the high-carbon steel after weaving silk after the lopping is in roller-way 1 operation of stelmo line, roller-way 1 below is provided with blower fan 3, air door 8 places of described blower fan 3 are provided with atomizer 4 through support 5, described atomizer 4 is by the outer tube that is provided with water filling port 4.1 and be provided with the inner sleeve 4.4 of air inlet 4.3 and the mouth core 4.5 that is communicated with inside and outside sleeve pipe 4.2,4.3, water inlet pipe 6 is communicated with water filling port 4.1, and air inlet pipe 7 is communicated with air inlet 4.3.
Operation principle: compressed air and cooling water are sent into through air inlet pipe 7 and water inlet pipe 6 respectively and are positioned at air door 8 place's atomizers 4, by 4.5 ejections of mouth core, and are evacuated to the wind in the roller-way 1 by blower fan 3 transhipments and contact the purpose that reaches quick cooling wire rod with wire rod 2.
The contrast experiment: when producing ф 8.0mm carbon spring steel, adopted the utility model and the no aerosol cooling blower that the atomizing cooling is arranged respectively at 1# blower fan place, and wire rod has been carried out thermometric, temperature-measuring results sees Table 1:
The thermometric contrast table of table 1 ф 8.0mm carbon spring steel wire rod (/ ℃)
| Fans entrance | In the middle of the blower fan | The blower fan outlet | |
| The aerosol cooling is arranged | 880 | 792 | 742 |
| No aerosol cooling | 880 | 817 | 765 |
| The temperature difference | 0 | 25 | 23 |
As can be seen from the table, adopt the wire surface temperature of the utility model cooling than low 23～25 ℃ of the temperature that does not have the aerosol cooling
